SPECIFICATION forming part of Letters Patent 0. 495,006, dated April 11, 1893.

Application filed March 18, 1891. Serial No. 385,515. (No model.) I

' .Be it known that 1, JOHN BAKER,'a citizen of the United States of Americaresiding at Muscatine, in the county of Muscatine and State of Iowa, haveinvented certain new and useful Improvements in'Detachable Link Belting, of which the following is aspecifi- J catioinrefcrencebeing had therein to theac- Thisiinvention consists in an improved ing as hereinafter described and claimed.

In the-accompan yin g drawingsFigure 1 is a plan view, of two links provided with my improvements, the'links being shown as connected. Fig. 2 is an edge View of the same.

Fig.3 is alongitudinal section taken on the .line ro-a: off-Fig. 1. Fig. 4: illustrates the manner ofsconnecting the links. 1 Each of the links is mainly in .the form of a rectangular frame, having side-barsA which are connected by a cross-bar B at one end, the said bar Bbeing round in section and intended to rest ina hook of an adjoining li'nk. 0 indicates a cross-bar at the, opposite end of the link, from which extend s a hook Dwhich is formed to reccive a cross-bar B of another link. The hook D is made of suitable width guides 62 in connecting or disconnecting the links. The guides 01 project from the inner sides of the side-bars A and are located opposite each other a short distance from the cross-bar B,thehook I), when adjusted in o place, occupying the spaces between the guides-and said bar B. In connecting the links, the hook D of one link is passed through another link which is turned to the position turned nearlyto avci'tical position. with the hook euddownward, sothat by drawing the shown in Fig. 4:, which represents the hook of 'a'link A passed through a linkjA' which is .45

link- A downward, thecross-bar B maybe brought into the hook of the link A, the v a 5 the edges 1) of the hook, when the linkA' may guides cl passing through the notches c in be turned toithe level position ofthe link A. In detachinga link, it is simply turned downward, on its cross-bar B, until the guides 01 are under the notches 0, when the link may 'be pushed upward, raising thebar B, from the hook in which it rested, and the guides throngh the notches c. structed may be readily connected or detached, but are not liable to become separated or detached when in use.

. I claim A series of detachable links, each of which is provided with sidebars having stops or guides d on their inner sides,a cylindrical cross bar at one end and a cross-bar at the The links thus con-- opposite end provided with a hook, adapted I and described.

In testimony whereof I have affixed my signature in presence of two witnesses.
